For homeowners wanting to expand floor space without encroaching into gardens, double storey extensions in Dartford offer a high-impact solution. They add usable room above and below, raising your home’s footprint vertically rather than horizontally.
Design & Layout Strategies
A well-designed double storey extension should balance upstairs and downstairs functionality. You might place extra bedrooms or a bathroom upstairs, and new living or dining areas on the ground floor. Matching roof lines, materials, and window styles helps the extension blend with the original structure. Using high ceilings or roof lights adds a sense of spaciousness.
Planning Permission & Regulations
Double storey extensions almost always require planning permission in Dartford, especially in conservation or tightly spaced areas. Neighbour consultation (Party Wall Act) becomes critical. Pay attention to overshadowing, overlooking, and adherence to boundary limits. Engage with your local planning office early and include accurate drawings.
Structural & Groundwork Essentials
Because you’re stacking weight, the foundations must be deeper and stronger, often needing piling or reinforced footings depending on soil conditions. Careful drainage, waterproofing, and structural support (beams, lintels) are key. Even small errors can lead to long-term movement or cracking.
